End User License Agreement (EULA)

Last Updated: November 05, 2026

1. Introduction & Contracting Parties

This End User License Agreement (“Agreement” or “EULA”) is a legally binding contract between you (“User” or “you”) and Aicrosoft (“we”, “us”, or “Developer”) governing your use of the KinTime mobile application (the “Application” or “KinTime”). The Application is licensed, not sold, to you for use strictly in accordance with the terms of this Agreement through official app distribution channels.

By downloading, installing, accessing, or using the Application from the Apple App Store, Google Play Store, or any other officially authorized distribution platform, you acknowledge that you have read, understood, and agree to be bound by all terms and conditions of this Agreement. If you do not agree to the terms of this Agreement, do not download, install, or use the Application, and delete it immediately from your device(s).

For information on how we handle personal information and our local-first architecture, please review our Privacy Policy. For information on tool neutrality and our non-medical advice disclaimer, please review our Disclaimer.

2. Software License Grant & Restrictions

2.1 Scope of License

We grant you a personal, revocable, non-exclusive, non-transferable, non-sublicensable, limited license to download, install, and execute the Application on mobile devices running iOS or Android that you legally own or control, solely for personal, non-commercial purposes, and strictly subject to the usage rules set forth in the applicable app store terms of service.

2.2 Restrictions

You expressly agree and warrant that you will not:

1. Decompile, reverse engineer, disassemble, or attempt to derive or reconstruct the source code, underlying algorithms, user interface designs, timing engines, or encrypted archiving mechanisms of the Application;
2. Circumvent, disable, tamper with, or breach any security sandbox boundaries, in-app purchase validation mechanisms, or digital rights protection measures implemented within the Application;
3. Rent, lease, lend, sell, sublicense, distribute, publish via public mirrors, or make the Application available to any third party as part of a commercial service;
4. Modify, adapt, translate, or create derivative works based upon the Application or any of its visual assets;
5. Use the Application for any purpose that violates applicable laws, regulations, public order, or moral standards, or infringes upon the legal rights and interests of others.

3. Business Model & In-App Purchases (IAP)

The Application operates under a “Local Lightweight Free + In-App Purchase (IAP) Pro Unlock” model:

1. Free Tier:
   • Includes core baby milestone tracking, birthday countdowns, basic timeline recording, and lightweight local photo albums;
   • The Free Tier may apply a reasonable quota limit on the number of family member profiles you can create.
2. Pro / Lifetime Tier:
   • Pro Privileges: Unlimited family member profiles, multi-dimensional milestone growth trend charts, exclusive commemorative theme styles, and batch lossless high-resolution data export;
   • Billing & Processing: All in-app purchase transactions are processed directly by the official app store billing systems (Apple StoreKit 2 or Google Play Billing). The Developer does not access, collect, or store your credit card numbers or financial credentials;
   • Lifetime License Definition: If you purchase a one-time “Lifetime” license, “lifetime” refers to the commercial lifecycle during which the Application continues to be actively maintained, operated, and made available to the public by the Developer, rather than the physical lifespan of the individual user.

4. Family Member Portraits & Guardian Rights

• Guardian Authorization Warranty: The Application is designed to record precious growth milestones of newborns, infants, and family members. When creating family profiles, inputting birth dates, and uploading facial photographs, you expressly represent and warrant that you are the legal guardian of the minor, or that you have obtained full informed consent and explicit authorization from the family member and/or their legal guardian.
• Self-Determined Portrait Data Security: Given the highly sensitive and private nature of family photographs and minor portraits, the Application strictly adheres to a local-first architecture without cloud facial recognition or centralized galleries. Users retain full data sovereignty, autonomy, and custody over all family image assets.

5. Intellectual Property & Reservation of Rights

All copyrights, trademarks, trade secrets, patents, and other intellectual property rights in and to the Application (including but not limited to source code, algorithms, interface interactions, UI icons, illustrations, trademarks, and documentation) are the exclusive property of Aicrosoft and its licensors. All rights not expressly granted to you under this Agreement are reserved by us.

6. Limited Warranty & Limitation of Liability

To the maximum extent permitted by applicable law, the Application is provided on an “AS-IS” and “AS-AVAILABLE” basis without warranty of any kind, whether express, implied, or statutory. The Developer does not warrant that the Application will operate error-free on all hardware configurations, remain compatible with all future operating system updates, or be immune to data loss resulting from force majeure. Under no circumstances shall the Developer’s aggregate liability to you for any and all claims arising out of or related to the use of or inability to use the Application exceed the total amount of legal currency actually paid by you for the Application or its in-app features.

7. Termination & Governing Law

• Termination: This Agreement and the license granted hereunder will terminate automatically without notice if you fail to comply with any of its terms. Upon termination, you must cease all use of the Application and permanently delete it from all devices.
• Governing Law & Dispute Resolution: The validity, interpretation, performance, and resolution of disputes under this Agreement shall be governed by the laws of the People’s Republic of China (excluding conflict of laws principles). Any dispute arising out of or in connection with this Agreement shall first be resolved through friendly negotiation; if no settlement is reached, the dispute shall be submitted to the competent people’s court where the Developer is located.
